Answer:
A. regulating eating behavior and how we respond to stress
Step-by-step explanation:
Endorphins, also called happiness hormones, are chemicals produced by the body itself that are structurally very similar to opioids but without their negative effects. These natural chemicals produce strong analgesia, stimulate the pleasure centers of the brain, creating satisfying situations that help to eliminate discomfort and decrease painful sensations. When we feel pain, endorphins act as endogenous pain relievers, inhibiting the transmission of pain to the brain.
